About this calculator

Estimate how much frying oil you need for a fish fry based on fryer size, batch count, and oil depth so you never run short or over-buy.

How much oil depth do I need for frying fish?

Most deep fryers need 3 to 4 inches of oil to fully submerge fish fillets without overflowing when food is added.

Why add extra for topping off?

Oil absorbs into breading and evaporates during long fry sessions, so you'll typically need to top off the fryer between batches.

How many times can I reuse frying oil?

Clean, filtered oil used for fish can typically be reused 2-4 times before flavor and quality degrade noticeably.
